I haven't gotten too far into it, just to the John Galt Line - and Hank Riordan discovering a moment of generosity. But it is absolutely phenomenal, better than anything I have read before.
I am adoring Ayn Rand's writing form and words she uses. It makes you think you are in a world of pure intellectuals, but the reader finds themselves swiftly brought back down to Earth after hearing the words and beliefs they utter. Take this statement as proof -- this is a conversation between Hank Riordan and his mother concerning Riordan's brother and his mother's desire that he be offered a job at Riordan's steel mill; a position he does not deserve and would not be able to do:

"That's your cruelty, that's what's mean and selfish about you. If you loved your brother, you'd give him a job he didn't deserve, precisely because he didn't deserve it -- that would be true love and kindness and brotherhood. Else what's love for? If a man deserves a job, there's no virtue in giving it to him, Virtue is the giving of the undeserved"

To which Riordan replies:

He was looking at her like a child at an unfamiliar nightmare, incredulity preventing it from becoming horror. "Mother" he said slowly, "you don't know what you're saying. I'm not able ever to despise you enough to believe that you mean it."
